World Population A low-projection scenario of world population for the years 1995–2150 by the United Nations is given by the function y = −0.36x2 + 38.52x + 5822.86, where x is the number of years after 1990 and the world population is measured in millions of people.

a. Graph this function for x = 0 to x = 120.
